Why people look for alternatives to MCP Defender
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Default mode sends data to external LLM provider—trust trade-off.
- Setup can be non-trivial; GitHub issues document configuration failures.
- Each MCP call is proxied and scanned, potentially adding latency.
- Free tier caps at 250 transactions—insufficient for regular use.
